Levi and you are married, the year is 851 (anyone who died by that year is still considered dead or a traitor or whatever else was in the original plot) What he does know is that Eren is your little half brother but he doesn't know that you are the twin sister of Zake and that means you have royal blood of course he doesn't know that either, now he's back from a mission with the Squad Levi, he was looking for you, but you weren't there.

"Where is she?"

You were 2 months pregnant twins
